Description
Technical field
The present invention relates to a kind of drill bits, and in particular to a kind of high-precision spiral bit.
Background technique
Drill bit is provided on drilling machine, the effect that process component can be drilled by the rotation of drill bit,
A large amount of iron filings can be generated when drilling, these iron filings can not timely repel the processing efficiency that drilling will lead to drilling
It is affected, the operation of efficient continuous drilling can not be carried out, need the intensity of drill bit fine when workpieces processing, in this way
The service life of drill bit can be extended, but many chisel edge intensity is inadequate, will affect drill bit subsequent drilling when
There is the case where bending in time, affects the actual use period of drill bit.
Summary of the invention
It is good that the object of the present invention is to provide a kind of intensity, connects a kind of high-precision spiral bit of fastening.
The technical solution of the present invention is as follows: a kind of high-precision spiral bit, is provided with knife handle, it is arranged in the knife handle
Drill bit, setting is nested between the knife handle and drill bit, extruding spring is provided on the drill bit, in the extruding spring
On be provided with outer convex block, the outer convex block and squeeze spring and be welded to each other fixation, welded between the nesting and knife handle solid
It is fixed, locking hole is provided in the nesting.
The drill bit is equipped with cutting slot, and the cutting slot is in the ramp-like two sides for being distributed in drill bit.
The cutting slot lower end is provided with cutting tip, and the cutting tip is hexagonal structure.
The cutting tip and cutting slot is connected with each other, and is provided with impact-resistant coating outside the cutting tip.
Impact-resistant coating on the cutting tip is corundum-coating.
The invention has the advantages that being provided with nesting on the knife handle, drill bit can be allowed to be fixed in nesting, passed through
Drill bit can be fixed in nesting by the interoperation of outer convex block and locking hole, pass through the cooperation of outer convex block and locking hole in this way
Movement can allow the handling enhanced convenience of drill bit that can carry out multiple replacement movement, and cutting is provided on the drill bit
Slot can allow drill bit timely to exclude iron filings by cutting slot when drilling to allow drill bit continuous in drilling
Bore operation, iron filings discharge drilling are more efficient.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is that the present invention strengthens plate schematic diagram.
1 is knife handle in figure, and 2 be drill bit, and 3 be nesting, and 4 is squeeze spring, and 5 be outer convex block, and 6 be cutting slot, and 7 be cutting point
